Adsorption Method for the Remediation of Brilliant Green Dye Using Halloysite Nanotube: Isotherm, Kinetic and Modeling Studies

The first-ever use of halloysite nanotube (HNT), a relatively low-cost nanomaterial abundantly available with minor toxicity for removing brilliant green dye from aqueous media, is reported. factors affecting adsorption were studied by assessing the capacity, kinetics, and equilibrium thermodynamic properties. All experiments designed at pH level around 7. Redlich-Peterson isotherm model fits best amongst nine models studied. kinetic studies data confirmed pseudo second order. Robotic investigations propose rate-controlling advance being overwhelmed intraparticle dispersion. adsorbent features interpreted using infrared spectroscopy electron microscopy. Process optimization was carried out Response Surface Methodology (RSM) through dual section Fractional Factorial Experimental Design to contemplate impact boundaries on course adsorption. examination fluctuation (ANOVA) utilized consider joined boundaries. possibilities adsorbing HNT (“sludge”) fabrication composites plastic waste are suggested.
